I am currently a beginner in asp.net i am currently watching msdn videos of "beginners developers learning" i am on the topic of application state so i got confused on a topic of "cross page postback" can anybody explain what that is
and another thing is "profile" object we use it in web.config file
1. what is cross page post back?
2. what is web.config file?
Is it possible to use cross-page postbacks (or a similar method, perhaps Server.Transfer) to post form data (say, Data-set A) to a page, which then allows the user to add some additional information (say, Data-set B) and then postback to the original page the complete set of data (A+B) which then flows through the normal event execution process, similar to as if all data A+B was submitted on the original page to itself in a normal postback?
I don't want the second page to have any type knowledge of the original page, it just needs to supply two additional feeds and send the data on. This way different pages and controls could use this method for gaining additional data.
For example:
Page 1 could have a form with various text inputs, and two hidden fields Hidden1 + Hidden2 which are empty.
When the form on page 1 is submitted the user is presented with page 2, they complete that page and then all the form data from page 1 is posted back to page 1 but with the hidden fields 1 + 2 complete. Page 1 then has all the information it needs to complete.
I'm thinking that perhaps page 2 just needs to use PreviousPage and take its post data, add to it and then post it back to page 1, but as if it came from Page 1 and not Page 2. But I'm not sure if this is possible and ASP.NET might read this as tampered data?
I am trying to create a static HTML page which has a <form> which posts to a 3rd-party ASP.NET website.
Is this possible when the target website uses ASP.NET webforms?
I have four textbox and a button in my page. After filling the textbox. When the user click save button. A loading image should be displayed. User should not feel that the page is postback to the server,Some thing like in facebook loading image.
View 5 RepliesBeing new to ASP.NET I have run into trouble building my own Whack-a-mole program. I think my problem comes from using Buttons, which by themselves send post backs to the server, making the software unusable. The looks are in place, making new buttons show up in the grid, in different places by random. However, when a button is pushed - the score doesn't change (which I feel is strange).
Not so strange is that the Button doesn't work since it sends post back to the server - reloading the UpdatePanel. I think I should use a different controller like the CheckBox and style it hard using CSS (which isn't a problem). Is this the correct way to go, or should I make use of JavaScript AJAX instead?
Note to self: This technique shouldn't be used in a public application since it put too much unwanted pressure on the web server.

View 4 RepliesI have a page that I am adding user controls to the bottom of the controls each postback. The User Control has a textbox in it and the focus needs to be on this newly created control textbox each time. It all works almost perfectly however when there are too many controls to fit on the page, because I set the focus to the textbox the bottom of the page is set to the textbox that has focus not the very bottom of the page. I have a submit button below this which ends up below the page limit. How can I set focus to a textbox but still scroll to the every bottom of the page to show the submit button.
View 1 RepliesI have an aspx page that postsback when it should not. there are two text boxes, two listboxes and two buttons on the page. if at any-point the enter key is pressed the first button is given focus and "clicked" resulting in a loss of selection within the listboxes.
How do I disable this? there are tons of tutorials on how to capture the enter button and execute a method but I could find one on how to simply disable the neat "let me grab the first button I find and click it" feature mentioned above.

View 7 RepliesI am writting an application that displays 3 visable text boxes and 1 hidden text box and one hidden button.
My application sets focus to the hidden text box.
The input comes from a barcode scanning gun which gives the "enter" command after the scan is complete...this essentially clicks the hidden submit button which moves the text from the hidden text box to the currently active visable text box.
To start the application does some verification on what was scanned then gives the user feedback on what was scanned then enters it into SQL.
My problem comes with the last scan...the page does not actually post back to give the user the neccessary confirmation before commiting the info to SQL and resetting the form.
Is there a way to either do somethig after the page has been rendered or do an additional post back somehow before calling the commit and reset functions?

View 2 RepliesI have an asp.net page "demo.aspx", that has a normal link called "Demo Link" which uses jQuery Thick box. The page that is wrapped inside the Thickbox is "target.aspx", that has a button "Demo Button" and a label.
If I click on the Demo Link, it show the "target.aspx" wrapped inside the Thickbox nicely. However, If I click on the "Demo Button", Thickbox is disappeared, "target.aspx" is not wrapped in Thickbox anymore, it is displayed like a normal asp.net page.
Here's the mark-up code of demo.aspx:
<a href="target.aspx?height=600&width=800" class="thickbox" title="">Testing Thickbox with Post-back</a>
Here's the code-behind of target.aspx:
Protected Sub btnDemo_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnDemo.Click
lblDemo.Text = "Hello World!"
End Sub
How do I keep target.aspx in the Thickbox after the post-back of itself?

I am using ASP.NET 2.0 with C#(No AJAX) in my project. In a particular web page, when the a button is clicked, some server intensive C# code runs before the same page is displayed again with the results. While code execution happens on the server in response to Button_Click event, a blank white page is shown to user on his browser in between post backs. How do i show a message in this case, that the processing is still going on and ask the user to wait? I have used javascript to show a message on page unload. But this message is also erased when the page is posted back to the server and the user sees a blank white page on his browser. How do i avoid this white page? Is there a way to show a message in the blank white page? How do i show a processing Message while the page is loading upon on Post Backs to the same Page.
View 1 RepliesI have a button like this:
<asp:Button ID="btnSave" runat="server" ClientIDMode="Static" Text="Save" OnClientClick="return ConfirmSave();" OnClick="btnSave_Click" />
If I write my client function like the following, it works as expected:
function ConfirmSave()
{
return confirm('Confirm?');
}
But I should check, inside the function, for the confirm result, like this:
function ConfirmSave()
{
if (Page_ClientValidate('validationGroup'))
{
var conf = confirm("Confirm?");
if (conf)
{
$('#btnSave').attr('disabled', 'disabled');
}
return conf;
}
else
return false;
}
Doing this, the page postback but the server click event doesn't fire.
I have been searching the net and found no clean cut answer to my problem. I have an animated spinning gif, that is displayed within an 'UpdateProgress'. This gif is to be displayed when the page is posting back to the server and processing.
The animation will start to spin but basically stright away it stops. I have noticed that the file menu within IE is also frozen at this point, up untill the page fully refreshes. I have tested in firefox and safari and am recieving the same problems.
